For example, when primed with the word "bank," the left hemisphere would be bias to define it as a place where money is stored, while the right hemisphere might define it as the shore of a river. The right hemisphere may extend this and may also associate the definition of a word with other words that are related.
The generation effect is typically achieved in cognitive psychology experiments by asking participants to generate words from word fragments. [2] This effect has also been demonstrated using a variety of other materials, such as when generating a word after being presented with its antonym, [3] synonym, [1] picture, [4] arithmetic problems, [2] [5] or keyword in a paragraph.

Free recall is one of the most commonly used recall tests. In free recall tests participants are asked to study a list of words and then are asked to recall the words in whatever order they choose to recall them in. The words the participants are to recall are typically presented one at a time and for a short duration.
In cognitive psychology, fast mapping is the term used for the hypothesized mental process whereby a new concept is learned (or a new hypothesis formed) based only on minimal exposure to a given unit of information (e.g., one exposure to a word in an informative context where its referent is present).
For example, there is some evidence to indicate that the grammatical gender of a noun is retrieved from the word's phonological form (the lexeme) rather than from the lemma. [4] This can be explained by models that do not assume a distinct level between the semantic and the phonological stages (and so lack a lemma representation). [3]
A model of the mental lexicon adapted from Stille et al. (2020) In the sample model of the mental lexicon pictured to the right, the mental lexicon is split into three parts under a hierarchical structure: the concept network (semantics), which is ranked above the lemma network (morphosyntax), which in turn is ranked above the phonological network.
The task is to identify the word that connects these three seemingly unrelated ones. In this example, the answer is salt. The link between words is associative, and does not follow rules of logic, concept formation or problem solving, and thus requires the respondent to work outside of these common heuristical constraints.
Studies have also been done to address the best method for recalling lists of unrelated words. In contrast to free recall, another type of study is known as the serial recall paradigm, where participants are asked to recall the presented items in their correct order rather than the order that comes to mind at the time of testing, randomly.
